Bioactive technology contained in FKS helps repair, rescue, renew and protect hair. FKS has the unique ability to actually restructure the hair by imbedding proteins into the hair, providing a permanent conditioning service. This product intelligently repairs the damaged areas of the hair, eliminating frizz, giving shine and health to the hair. To use FKS for a permanent conditioning service, the hair must be in reduced state (such as during a chemical service).
